All 4 is a free app, and our content is free to watch because we are a commercially funded public service broadcaster. As a publicly owned, not-for-profit organisation, the revenue we make from advertising doesn’t go to shareholders; it goes back into making more programmes.

Using Chromecast or outputting from a device to a TV requires specific rights, which we don't currently have for all of our programmes. As our rights come up for renewal this is something we are seeking to address wherever possible.

Needs work, but ok I know they need the adverts to fund the app, but 3 adverts before you get to the show you want to watch is a little excessive. I was also annoyed to find when I paused the app to talk to someone it took me back to the start when I resumed. I could forward the programme on the search bar but not the adverts. Change it to just one advert at the beginning & one in the break & it'd be worth 4 stars, get rid of the adverts & it'd be 5.

No support for rooted devices Despite claiming to be paid for and accountable to the viewer, apparently I'm not allowed to view content because I own and have rooted all my devices? I want to cash in my shares then.

No rooted devices?! My device is blocked because it's rooted? If I wanted to steal your shows I'd just torrent them. Rooting devices on android is really common, it doesn't mean that everyone's up to malicious activities. Great way to treat your viewers. Back to iPlayer I go I guess! It's a better app anyway.

No rooted devices..wow. Guess I'll just torrent my TV instead! So the anti root piracy policy has forced me to do exactly that. *clap clap* well done. Now more and more of the TV apps take this stance I've uninstalled them all and installed Kodi+Catchup TV addons. I now have everything in one app on my ROOTED device.

Battery or this Much like lots of your other users, I use a rooted device. In my case its to save battery and install custom ROMs. Not to pirate 'The Big Bang Theory'. If you think that stopping users with rooted devices watching your programmes will lower piracy rates, you're very wrong. In fact, I'd imagine more people will turn towards piracy to watch the shows on their devices if you won't support it. First the issue where no programmes played whatsoever and threw a connection error, now this. The old 4od worked.

Simply doesn't work! Well, the ads do. But if you wanted to watch any TV programmes, forget it. I didn't upgrade when prompted months ago due to the terrible reviews, but now that I have a new tablet, it's come installed with this version. So no more Channel 4 programmes for me. Are you letting your advertisers know that no-one's watching your programmes on mobile devices Channel 4?

Don't know why they even bother to make an app Although I like the content of channel 4 it's the app which fails to work well. For a company with such resources it should have been better. Downloads don't work. The download queue has been sitting for a week without a single programme downloaded despite good WiFi connection.

Not perfect But better than iPlayer in terms of its ability to resume a video when you read a notification. Same flaw that means you cannot download on a network, though, which is useless for anyone without WiFi at home (e.g. people who have embraced mobile contracts). Also, no ChromeCast support

Just turn root off guys? Okay so now instead of banning the ad blocker/screen rec. software which is causing the problem they impose a blanket ban on any rooted device. So I have to choose between root; backup, clock speed adjustment, battery saving apps and essential features or all 4 (aka 4od). I don't know if anyone at channel 4 has a android which is rooted however there is no off button (f.y.i). This is on top of other complaints like no chrome cast (because of their tiff with Google) and twice as long ad times as itv player.

Latest versions don't work on rooted phones Older phones often get rooted to get access to decent operating systems; it's as simple as that. Not some Machiavellian plot to rip off your intellectual property. Please consider allowing rooted phones to watch your catch up content.

Still Disappointing Well, well, what have we here? A newly rebranded app complete with a nice makeover. Someone at Channel 4 should be very proud. But. STILL no Chromecast support and still too many ads. Now this isn't the fault of the team who built this, they should be rightfully proud of this work. It's hampered by dumb "rights management" (actually restrictions), which allow the PlayStation 3 app to work on my telly but not the Chromecast and dumb commercial thinking which means too many ads for a small screen.

No Chromecast support still! It's a poor excuse that your contracts don't allow us to cast. You clearly don't know much about casting, as your mobile doesn't stream the video from phone to TV, the TV/Chromecast just streams the video direct from your servers, with mobile acting as a remote control. How is this any different to watching All4 on my laptop, ps3, or tablet?! Technically my ps3 streams the video to my TV, so how is this any different. Clearly you chose to have a really specific contract, or your legal team is wrong!

Awful Such a shame. I honestly don't know how you managed to make such a mess of this app. Funny how all the adverts play fine, yet it's almost impossible to steam any shows, despite having registered and given you my address. Steer well clear, a waste of time :(

Started well, audio and image breaks This App has performed well over the last few months, however recently on my Xperia tablet the audio and visual play breaks every couple of minutes on numerous programs. It is unwatchable. Sort it out please - Chromecast would be great too

Works perfectly but...... Love the way it's so easy to find the shows. Not loving the length of the ads though. I get that you need to get paid and that's fair enough, but there is an awful lot of ads. Also why no chrome cast? That's a big feature that your missing.

The selection of programmes is excellent. BUT the app crashes after every set of advert breaks. I understand channel 4 is funded through ads but getting us to watch them over and over is too much. This app is far too unstable to be enjoyable nor useful. I will not be purchasing anything advertised in protest of that waste of my time. My devices are not rooted.

Loved it Beause it's so amazing you can watch anything you want that on 4od. I am seriously freaking out right now because of how brilliantly 4od is wow I never been this excited ever in my life. Thank you the poeple who made it for making it. I am so amazed right now.

It is free if you don't mind 5 minutes of adverts. Not worth considering, cannot ping over to the TV using chromecast "4 does not allow". Overall it's an ugly app. I'd prefer to leave 0/5 stars, but 1 is the lowest.

Audio and video play at different times I have streamed and downloaded, the adverts are top notch and work without a hitch! The actual content freezes randomly and the audio stops playing. Please sort it out!

No rooted phones?! Like many previous reviewers have said, this is a ridiculous and ultimately pointless policy as I will, like most others, just watch C4 content by another (probably ad free) method. I guess the reasons are due to the app having the ability to store downloaded programmes? How about making an 'All4 lite' that just let's us view the shows? I'm pretty sure that all of us using older, rooted devices don't have the space to be downloading full shows anyway!!

Gone from 4* to 1* & I'm not rooted! 4od should be applauded as the first UK TV platform I'm aware of that gave android users downloads, while the BBC was busy getting into bed with Apple. I don't mind ads - you have to pay for good content somehow. Sadly, now it's All4, all I can see are the ads (perfectly well) before I'm told I have a connectivity issue and can't play the program. On an HTC One M8 with perfect connection.

Many Flaws (BTW, dumb name) Lack of casting support is very annoying. As is the lack of Fire TV or Nexus Player App. Having to get out my laptop whenever I want to watch All 4 on my telly is most frustrating - as a result is I don't. I watch Netflix or Amazon Prime or iPlayer or rent something. Given that Channel 4 are funded largely from advertisements, you'd think they would do all they can to make viewing as pain free as possible. They would get more viewers, and therefore would require fewer adverts, and therefore get more vi...

I would give 0 stars if I could but... Unfortunately I am forced to give 1 star!... The first thing to note is that All4 does not support rooted devices. "For security reasons and to protect the rights of our content partners"... By blocking rooted users you are more likely to encourage/force ones to view your content by other means, ad free means at that.

Constant freezing Doesn't matter which device I use, tablet or ps3, it freezes over and over in the ads. It spends more time frozen than it does playing any of the show I'm trying to watch. I didn't give it less than 2 because sometimes it actually works, and at least there's a wide selection of stuff to watch.

Sort it out C4 This app worked lovely now I cannot even watch for 5 mins with out the steaming freezing or a comment saying that there is a network problem please check your network connection and try again!! Nought wrong my end!! Totally annoyed!

Black Screen! Well done channel 4 on making the worst on demand app in the UK! No chromecast support! At best keeps crashing! The rest of the time it's just a black screen instead of playing anything! I'd suggest you pay the BBC a visit and see how they make the iPlayer work so well.

Daft WiFi restriction This app alows you to stream programmes over 3G/4G, however it does not allow you to download programmes unless you have a WiFi connection. As someone who pays a lot of money for unlimited 4G data I find this unacceptable and frankly pathetic.

And now even blocking rooted devices! Rooting is the first thing I do on a new phone, not to get around copyright (much easier to do on a pc! ) so choice between your app and that is easy! Don't want to watch tv on my phone, I want to watch on my tv. Since neither my Panasonic viera tv, sony bluray or wdtv media streamer have a 4od app (all have bbc iplayer though), I was hoping to use this app to miracast to my tv. There's apps on several devices, so can't see how you can't have the rights to cast from this app!

Can only be described as an epic fail Another update another failure. Not rooted - stock ee htc m8. The only people that might be happy with this app on this platform and device are the advertisers that you clearly can stream but not the programs you promise we can watch. Utter drivel, seriously, who did your sit and uat? Appalling

Brilliant if you love just watching adverts Adverts play fine, programmes not at all. Apparently my network connection is too slow! This I am very dubious about as am happily streaming hd elsewhere. Just don't waste the 1:30 of your time watching the adverts to find out and go do something else!

Just doesn't work This app used to work fine in the old days when it was 4OD,now they have updated it and its worse than useless. Very disappointed, love the shows, just cant watch them anymore. Come on channel4, read your reviews and DO something please.

Terrible app... Adverts work fine... On tablet the adverts work fine (funny that), but any program stops playing every few seconds.. video freezes and audio then catches up.. absolutely terrible app and this ruins any of the VERY SMALL number of channel 4 programmes that are actually worth watching!

Useless... Still no DNLA or even Chromecast support, why..? This app is useless on a phone... it's not even intuitive. How can you guys at Ch4 mess this up ao badly? Aren't you embarrassed with such a low star rating? Cmon... get with it...

Needs improvement Too many as (more than TV) no Chromecast support and, although I haven't bothered to root my device yet, I'd really like the option (for one of the many reasonable and perfectly legal reasons to root)

Stupid update... wtf Was working and absolutely loved it, then this app popped up needing a update to be used.. so updated and since then its a load of crap.. cant play anything... just because my phone is rooted its a stupid ban. Aint happy just wanted to watch my shows and enjoy! Why change something when it isnt broken... complete twits youve lost a load of viewers by doing this.. Thanks for nothing All 4!!
